How to Use Oil Pastels: Techniques for Beginners

Oil pastels sit somewhere between crayons and oil paint. They are pigment held in wax and non-drying oil, so they glide on with rich color, blend easily and stay slightly soft forever. That softness is their charm and their challenge: press too hard too early and the paper’s tooth fills up, leaving nowhere for the next layer to go.

This guide explains how to use oil pastels step by step, from choosing paper to blending, layering, special techniques and protecting finished work. For deeper coverage of tools and combined oil and pastel methods, see our guide to oil paint pastel techniques, tools and tips.

What Makes Oil Pastels Different

Because they never fully dry, oil pastels do not produce dust like soft pastels, but the finished surface remains vulnerable to smudging and needs protection.

Materials You Need

• Oil pastels: A set of 24–48 colors is plenty to start. Student sets are firmer; artist-grade sticks are softer and more pigmented.
• Paper or board: Pastel paper, heavy drawing paper (around 150 gsm or heavier), mixed-media paper, watercolor paper, or primed board. Sanded pastel papers hold many layers.
• Blending tools: Fingers, paper blending stumps (tortillons), cotton swabs, a colorless blender stick, color shapers (silicone-tipped tools).
• Scratching tools: A palette knife, toothpick, skewer or dried-out ballpoint pen for sgraffito.
• Cleanup: Paper towels or baby wipes for cleaning sticks and fingers.
• Optional solvent or oil: Baby oil, mineral oil, or odorless mineral spirits with an old brush for painterly blending.

Choosing a Surface

Surface tooth (texture) controls how many layers you can apply. Smooth paper fills quickly and makes colors slide; textured paper grips more pigment.

Colored papers save time: a mid-tone sheet lets you work both lighter and darker without covering every bit of white.

How to Use Oil Pastels for Beginners: Step-by-Step

1. Sketch lightly. Use a pastel in a light, neutral color or a pale colored pencil. Avoid heavy graphite, which can smear into light colors.
2. Block in with light pressure. Lay down the main color areas using the side of the stick or light strokes. Keep it thin so the paper’s tooth stays open.
3. Start light, go dark. In general, apply lighter colors first, then darker ones on top. Light colors are hard to place cleanly over heavy dark layers.
4. Build layers gradually. Add a second and third layer with slightly more pressure, mixing colors optically and physically on the paper.
5. Blend selectively. Soften transitions where you want smooth gradients, such as skies or skin. Leave texture elsewhere.
6. Add details and highlights last. Use heavy pressure, a sharp edge of the stick, or a white pastel pressed hard into the surface for final highlights.
7. Refine with sgraffito. Scratch into layers to reveal colors beneath for fine lines like hair, grass or texture.

Holding the Stick and Basic Strokes

How you hold an oil pastel changes the mark as much as which color you choose.

• Tip, held like a pencil: For lines, outlines and small details. Rotate the stick as you work to keep an edge.
• Side, held flat: Peel back or remove the paper wrapper and break off a short piece. Drag it sideways for broad, even coverage of skies and backgrounds.
• Broken edge: Snapping a stick gives a sharp, angular edge useful for crisp details.
• Short dabs: Quick, short strokes create texture for foliage, fur or grass.
• Directional strokes: Following the shape of an object (around an apple, along a tree trunk) makes forms look more three-dimensional.

Don’t be afraid to break sticks. Short pieces are easier to control for side strokes, and most artists end up with a box of fragments.

Mixing Colors With Oil Pastels

Unlike paint, you cannot premix oil pastels on a palette in the usual way, so color mixing happens on the paper. A few principles help:

1. Layer, don’t stir. Place one color lightly, then a second over it. Two thin layers mix more cleanly than one heavy, rubbed mess.
2. Use complements in shadows. A touch of violet over a yellow object’s shadow, or green over red, gives richer darks than black.
3. Use optical mixing. Small strokes or dots of two colors side by side read as a third color from a distance and stay vibrant.
4. Limit layers per area. Three or four colors in one spot is usually the maximum before it turns muddy.

Practice Exercises

• Gradient strip: Blend from one color to another across a 6-inch strip using three different blending methods, and compare.
• Value sphere: Draw a ball with one color plus white and a dark, showing light, mid-tone, shadow and cast shadow.
• Sgraffito sampler: Fill a square with bright colors, cover with black, then scratch patterns.
• Sunset study: Layer yellow, orange, pink and violet horizontally, blending each transition.

Oil Pastel Blending Techniques

Layer blending

Apply one color, then a second over it with moderate pressure. The pastels mix on the paper as you work. This keeps colors fresh and is the most controllable method.

Finger blending

Rub gently with a fingertip. Body warmth softens the pastel and helps it merge. Clean fingers often to avoid carrying colors around; some artists wear a finger cot or glove.

Tool blending

Blending stumps, cotton swabs and silicone color shapers give more precise blending than fingers. Wipe them clean between colors.

Colorless blender

A colorless blender is an oil pastel without pigment. Rub it over two colors to merge them smoothly, or over a single color to make it more transparent.

Solvent or oil blending

Dip an old brush in a small amount of baby oil, mineral oil or odorless mineral spirits and work it into the pastel. It dissolves into a paint-like wash. Use this on heavy paper or board, as liquids can soak through thin paper, and ventilate if you use solvents.

White blending

Layering white over a color, then blending, creates soft tints and gradients. Remember that white also lightens; keep a separate clean white for pure highlights.

Special Oil Pastel Techniques

Sgraffito

Lay a light color, then cover it with a dark one. Scratch through the top layer with a toothpick or knife to reveal the light color. Great for patterns, hair, grass and lettering.

Scumbling

Use the side of the stick lightly over a dry-looking textured layer so color catches only the high points. It creates broken, atmospheric effects.

Stippling

Make small dots of different colors close together. From a distance they mix optically, like pointillism.

Impasto

Press soft pastels thickly onto board, or apply with a palette knife after warming the pastel slightly. The result looks almost like oil paint.

Resist with watercolor

Draw with oil pastels on watercolor paper, then paint a watercolor wash over the top. The wax and oil repel the water, so the pastel marks stay crisp. Children and adults alike enjoy this for night skies and underwater scenes.

Crosshatching and hatching

Build color with parallel or crossing lines. It keeps the texture visible and allows gradual color shifts.

Common Mistakes and Fixes

Keeping Your Pastels Clean

Oil pastels pick up color from every layer they touch, so a yellow stick can turn greenish after one pass over blue. Wipe the tip on a paper towel after each use on a dark area. Some artists store each stick in a shallow tray of uncooked rice and shake it gently; the rice scrubs off surface residue. Keep sticks in their original box slots or a divided tray so they are easy to find and do not rub against each other.

Fixing a Mistake

• Scrape off excess with a palette knife, then work lightly back in.
• Lift residue with a kneaded eraser pressed (not rubbed) on the area, or a piece of tape lightly dabbed on.
• Cover with an opaque color, especially white or a light opaque mix, then rework.
• For large problems on board, a cloth with a little baby oil can remove more pigment.

Protecting Finished Oil Pastel Art

Oil pastels do not dry or harden, so finished pieces can smudge for years.

• Fixative: Use a fixative made specifically for oil pastels, which forms a protective coating. Regular soft-pastel or charcoal fixatives may not work well. Spray outdoors or in a well-ventilated space.
• Framing: Frame under glass with a mat so the surface does not touch the glass.
• Storage: Store flat with glassine or parchment paper between sheets.

Combining Oil Pastels With Other Media

Oil pastels work well over dry acrylic or watercolor underpaintings, which let you establish big color areas quickly before adding pastel texture on top. They can also be used over dry oil paint. Avoid putting water-based media over oil pastel, other than as a deliberate resist, because it will not adhere. Oil paint can go over oil pastel, but since the pastel never fully hardens, the bond may stay weak, so keep such experiments to studies.

Tips by Skill Level

Beginners

Use a limited range of 10–12 colors at first to learn mixing. Practice simple subjects such as fruit, sunsets or landscapes with big shapes. Try a color gradient exercise: blend two colors smoothly across a strip.

Intermediate

Experiment with toned papers, sgraffito and solvent blending. Start using complementary colors in shadows rather than black.

Advanced

Combine artist-grade soft pastels with firmer student pastels: firm sticks for early layers and details, soft sticks for final rich layers. Try large works on primed board and mixed-media combinations with oil paint.

FAQs

Do you need special paper for oil pastels?

Not strictly, but heavy paper with some tooth works much better. Pastel paper, mixed-media paper, watercolor paper or primed board all hold more layers than smooth printer or sketch paper.

How do you blend oil pastels without a blender?

Layer colors with firm pressure, rub with a fingertip, or use cotton swabs or paper stumps. A little baby oil on a brush also blends.

Can you mix oil pastels with water?

No. Oil pastels repel water, which is why they work as a resist under watercolor. To liquefy them, use oil or odorless mineral spirits.

Do oil pastels ever dry?

Traditional oil pastels do not fully dry because their oil does not oxidize. They stay soft and can smudge, so protect finished work.

Should I start with light or dark colors?

Generally light colors first, then darker ones. Reserve the brightest highlights for the very end, applied with firm pressure.

How do you make oil pastels look like paint?

Apply thick layers on board, blend with a little oil or solvent on a brush, and use palette-knife impasto for texture.

Final Thoughts

The key to oil pastels is patience with pressure. Light, layered early passages keep the surface open, and heavier strokes at the end give rich color and crisp highlights. Once you have that rhythm, blending, sgraffito and mixed techniques follow naturally.
